This post goes over how to count issues with Jira REST API.

Create an API token

Create an API token from your Atlassian account.

See “Manage API tokens for your Atlassian account” for more details.

Search for issues using JQL

Search for issues using JQL (POST):

// index.js
fetch(`${process.env.JIRA_DOMAIN}/rest/api/3/search`, {
  method: 'POST',
  headers: {
    Authorization: `Basic ${Buffer.from(
      `${process.env.JIRA_EMAIL}:${process.env.JIRA_TOKEN}`
    ).toString('base64')}`,
    Accept: 'application/json',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    // update JQL
    jql: `project = "My Jira Project" AND issuetype in (Story, Bug, Task) AND resolution = Done`,
    maxResults: 0,
  }),
})
  .then((response) => {
    console.log(`Response: ${response.status} ${response.statusText}`);
    return response.json();
  })
  .then((json) => console.log(json))
  .catch((error) => console.error(error));

Set the environment variables:

Environment Variable	Example
JIRA_DOMAIN	https://my-domain.atlassian.net
JIRA_EMAIL	[email protected]
JIRA_TOKEN	ABCDEFGHIJKLMNOPQRSTUVWXYZabc123

Update the jql to include resolved date and assignee:

project = "My Jira Project" AND issuetype in (Story, Bug, Task) AND resolution = Done AND resolved >= 2023-01-01 AND resolved < 2024-01-01 AND assignee = abcdef1234567890abcdef12

Run the Node.js script with your environment variables:

node index.js

The response will look like:

{ "startAt": 0, "maxResults": 0, "total": 42, "issues": [] }
